Performance effects of application programming interfaces (API). What is the impact of distinct design choices and value creation strategies?
Seminar paper from the year 2021 in the subject Computer Science - Commercial Information Technology, grade: 1,0, University of G繹ttingen (Wirtschaftswissenschaftliche Fakult瓣t), course: Selected Issues in Digitalization, language: English, abstract: This paper is about Application Programming Interface and methodology and results, contribution and implications and Further research. The rise of digital platforms in recent years induced a substantial emergence of Application Programming Interfaces (APIs) at business organizations. By connecting two parties with mutual interests, APIs facilitate digital collaboration and generate network effects beneficial to both. This literature review examines a research conducted on the performance effects of APIs. It measures the potential impact of distinct design choices and value creation strategies on the commercial outcome and pervasion of an API. The results suggest that API design must be deliberately coordinated with the strategy of value creation in order to achieve desirable business objectives. The findings are demonstrated with a case study on open banking as a practical example. Moreover, the paper is contextualized with two related journal articles, validating and extending the insights found.

Pandas Brain Teasers
This book contains 25 short programs that will challenge your understanding of Pandas. Like any big project, the Pandas developers had to make some design decisions that at times seem surprising. This book uses those quirks as a teaching opportunity. By understanding the gaps in your knowledge, you'll become better at what you do. Some of the teasers are from the author's experience shipping bugs to production, and some from others doing the same. Teasers and puzzles are fun, and learning how to solve them can teach you to avoid programming mistakes and maybe even impress your colleagues and future employers. Working with data is central to nearly everything we do, from disease contact tracing and analyzing health records to smart meters that track utility consumption behavior. With the power of Python's pandas library, you can process and analyze this data in a highly efficient and simple-to-understand way. And with 25 brain teasers designed to turn this technology's quirks into a teaching opportunity, you'll be honing your data science skills while having fun at the same time. Following a simple format, you'll challenge yourself and your understanding of pandas. Read a short Python program that uses pandas, try to guess the output, run the code yourself, and then go to the next page for an explanation of the solution. From common pitfalls and hidden gotchas to unexpected twists and turns, you'll deepen your understanding of pandas, learn to write more efficient code, and reduce the number of bugs in the software you develop. You may even impress your colleagues and your employers, both present and future. Learn the tricks of the trade with Python's pandas, in one of the most fun and creative ways around. What You Need: To run the code you'll need Python version 3.8 or upper and Pandas version 1.0 or upper installed. We use Python version 3.8.3 and Pandas version 1.0.5; the output might change in future versions.

Bachelorarbeit aus dem Jahr 2020 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,3, Internationale Fachhochschule Bad Honnef - Bonn, Sprache: Deutsch, Abstract: Die rasche Weiterentwicklung der Smartphones und ihre immer weiter voranschreitende Durchdringung des betriebswirtschaftlichen Umfelds bringen neue Herausforderungen f羹r die Benutzerfreundlichkeit mit sich. Diese Entwicklung betrifft auch das Enterprise Resource Planning (ERP) des deutschen Softwareunternehmens SAP. Durch das neue moderne Designsystem SAP Fiori k繹nnen betriebswirtschaftliche Anwendungen im Browser des Smartphones verwendet werden. Zur Bewertung der Benutzerfreundlichkeit ist die heuristische Evaluation (HE) eine der gebr瓣uchlichsten Methoden, da es unkompliziert ist, eine Bewertung der sich in Entwicklung befindenden Software anhand einer Reihe von Designprinzipien durchzuf羹hren. Diese Studie zielt auf die Entwicklung von mobilen webbasierten SAP Fiori-Apps ab und stellt eine Usability-Checkliste von User Interface Design Heuristiken zusammen. Diese wird um relevante Kriterien auf Grundlage valider und standardisierter Usability-Frageb繹gen, SAP Fiori Designrichtlinien und der Problembereiche mobiler Oberfl瓣chen erweitert. Damit die Effizienz der Checkliste 羹berpr羹ft werden kann, werden zwei Prototypen entwickelt und durch zwei Gruppen mit jeweils f羹nf Versuchspersonen in einem Usability-Test im Labor evaluiert. Der erste Prototyp wird auf Grundlage der HE unter Verwendung der Checkliste von zwei Softwareingenieuren bewertet und zu einem zweiten Prototyp weiterentwickelt. Durch Mitschriften und Frageb繹gen w瓣hrend der Tests wird der Einfluss der Checkliste mittels einer qualitativen Inhaltsanalyse in verschiedenen Bereichen ausgewertet. Die Ergebnisse dieser Studie zeigen eine positive Tendenz der Checkliste zur Reduzierung von Usability-Problemen in vielen Teilbereichen wie beispielsweise der Formularbearbeitung und der Navigation.

Gesch瓣ftsprozessoptimierung in der Softwareentwicklung. Evaluierung von Methoden zur praktischen Umsetzung
Projektarbeit aus dem Jahr 2020 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,2, Hochschule Ravensburg-Weingarten, Veranstaltung: Projektseminar, Sprache: Deutsch, Abstract: Im Rahmen dieser Projektarbeit soll die Frage beantwortet werden, welche Methoden zur praktischen Umsetzung von Gesch瓣ftsprozessoptimierungen (Six Sigma, Lean Management, Kaizen, Agiles Prozessmanagement) in der Softwareentwicklung Anwendung finden k繹nnen. Die Hauptaufgabenstellung liegt darin, die verschiedenen Methoden auf die Softwareentwicklung zu adaptieren, zu evaluieren und miteinander zu vergleichen. Hierbei soll auch erl瓣utert werden, ob die Art des Projektes (Umfang, Thema, et cetera) die Eignung der Methoden zur Gesch瓣ftsprozessoptimierung bestimmt. Des Weiteren soll er繹rtert werden, ob es Voraussetzungen oder Einflussfaktoren gibt, die das Projektteam oder das Unternehmen mitbringen m羹ssen, um den Erfolg der Gesch瓣ftsprozessoptimierung zu sichern. Seit der industriellen Revolution wurde die Produktivit瓣t durch Arbeitsteilung massiv erh繹ht. Dabei wurden komplexe Abl瓣ufe in kleine Schritte - Funktionen - zerlegt, welche durch darauf spezialisierte Mitarbeiter effektiv durchgef羹hrt werden konnten. Doch in der zweiten H瓣lfte des 20. Jahrhunderts f羹hrte die Konzentration auf Funktionen auch zu Nachteilen f羹r die Mitarbeiter. Des Weiteren stellte sich heraus, dass durch die Arbeitsteilung die Erf羹llung von Kundenw羹nschen, insbesondere bei Dienstleistungen, erschwert wird. Zus瓣tzlich ver瓣nderten sich die Anforderungen an Unternehmen durch die Digitalisierung und Globalisierung: Produkte wurden immer komplexer, Kundenanforderungen spielten eine gr繹?ere Rolle und durch den sich schnell ver瓣ndernden Markt sind Unternehmen zu einem hohem Ma? an Flexibilit瓣t gezwungen, wenn sie wettbewerbsf瓣hig bleiben wollen.
Die Verkn羹pfung von BIM und CAFM unter Ber羹cksichtigung des IoT. Eine Analyse zur Implementierung der Prozesse bei der E. Projektmanagement GmbH & Co. KG
Masterarbeit aus dem Jahr 2020 im Fachbereich Informatik - Internet der Dinge, IOT, Note: 1,0, EBZ Business School (ehem. Europ瓣isches Bildungszentrum der Wohnungs- und Immobilienwirtschaft), Sprache: Deutsch, Abstract: Das Ziel der Masterthesis ist, Bestandsprozesse von Projektentwicklungen der E. Projektmanagement GmbH & Co. KG zu analysieren, um darauf aufbauend das Building Information Modeling in Verkn羹pfung mit dem Computer Aided Facility Management und dem Internet of Things zu implementieren. Die Bestandsprozesse sind damit Grundlage daf羹r, welche Anpassungen in Bezug auf Prozesse und Anforderungen getroffen werden m羹ssen. Zur Erreichung des Ziels werden in einem ersten Schritt im zweiten Kapitel die Grundlagen erl瓣utert. Das Grundlagenkapitel unterteilt sich in die Themenbereiche Building Information Modeling, Computer Aided Facility Management und Internet of Things. In diesen Unterkapiteln werden die unterschiedlichen Technologien bzw. Methoden definiert, sodass bereits deutlich wird, welche Voraussetzungen in einem Unternehmen erforderlich sind, um die einzelnen Technologien zu nutzen. In den Grundlagen wird dar羹ber hinaus der Status Quo der einzelnen Technologien dargestellt. Im dritten Kapitel folgt die Analyse der Methodenverkn羹pfung. Die Methodenverkn羹pfung unterteilt sich in drei Unterkapitel. Zuallererst wird analysiert, wie BIM und CAFM miteinander verkn羹pft werden k繹nnen. Im Ergebnis werden unterschiedliche Integrationsstufen herausgefiltert, von denen die h繹chste Stufe detaillierter betrachtet wird. So werden die Bedingungen f羹r eine Stufe 3-Verkn羹pfung und die sich daraus ergebenden Herausforderungen dargestellt. Dabei wird ma?geblich Bezug auf die in Kapitel 2 erl瓣uterten Grundlagen genommen. In einem zweiten Schritt folgt die Methodenverkn羹pfung vom Internet of Things mit dem CAFM bzw. BIM. Es werden die f羹r das Facility Management relevanten IoT-Technologien dargestellt sowie die Ber羹cksichtigung in der Planung und der Realisation erl瓣u
Beurteilung der Qualit瓣t von Software. Software Benchmarking und die Entwicklung eines Plugins f羹r Sonarcube
Masterarbeit aus dem Jahr 2014 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1, Johannes Kepler Universit瓣t Linz (Institut f羹r Wirtschaftsinformatik - Software Engineering), Sprache: Deutsch, Abstract: Was ist Qualit瓣t von Software und wie kann man sie bestimmen? Beide Teile dieser Frage sind zentrales Thema dieser Arbeit. Zuerst wird versucht, eine Definition f羹r Software Qualit瓣t zu finden, bevor ein Vorgehen zur dessen Bestimmung, n瓣mlich das Software Benchmarking, vorgestellt wird. Die n瓣here Betrachtung des Benchmarkings f羹hrt anschlie?end zur Entwicklung eines Plug-Ins f羹r SonarQube, welches das Benchmarking der einzelnen Softwareprojekte erm繹glicht. Dieses Plug-In namens SBench errechnet, aufgrund der Regelverletzungen, alle vier Quartillen und ordnet die Projekte anschlie?end darin ein. Das Ergebnis wird in Form eines Boxplots und eines Benchmark Profils f羹r den Benutzer grafisch dargestellt. Die Anwendung des Plug-Ins zeigte, dass die Qualit瓣t der Projekte, im Vergleich zu den Referenzprojekten, sehr schnell eingesch瓣tzt werden konnte und sich die M繹glichkeit er繹ffnete gezielt Qualit瓣tsverbesserungen durchzuf羹hren. Das einzige Manko stellt die doch l瓣ngere Zeit in Anspruch nehmende Berechnung dar. Die Informations- und Kommunikationstechnologien haben in den letzten Jahrzehnten eine immer bedeutungsvollere Aufgabe erhalten. Mittlerweile ist eine Welt ohne Computer, Smartphones und anderen Rechner unvorstellbar. Sie sind Bestandteil des t瓣glichen Berufslebens, alle Bankgesch瓣fte werden mit ihrer Hilfe abgewickelt und in naher Zukunft wird es vermutlich m繹glich sein, ein ganzes Haus durch wenige Tastendrucke zu steuern. All diese eingesetzten Ger瓣te k繹nnten jedoch nicht die gew羹nschten Funktionalit瓣ten ausf羹hren, w羹rde auf ihnen nicht eine geeignete Software laufen. Ein St羹ck Software ist inzwischen in mehr Dingen enthalten, als man es sich jemals vorstellen konnte. Von der Waschmaschine, 羹ber Uhren bis hin zu Autos funktioniert alles nur noch
Grafikprozessoren und deren Architektur. Einblicke in die Parallelisierung und die Funktionsweise von Mehrkernprozessoren
Akademische Arbeit aus dem Jahr 2020 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1.0, FOM Hochschule f羹r Oekonomie & Management gemeinn羹tzige GmbH, Bonn fr羹her Fachhochschule, Veranstaltung: IT-Infrastruktur, Sprache: Deutsch, Abstract: Die folgende Arbeit zielt darauf ab, ein Verst瓣ndnis 羹ber die Funktionsweise und den Aufbau heutiger Grafikprozessoren zu vermitteln. Hierbei wird exemplarisch f羹r moderne GPU-Architekturen, die auf dem GP100-Chipsatz basierende Nvidia Pascal Architektur der GTX1000 Serie analysiert. Die Graphics Processing Unit (GPU) hat im Verlauf der letzten f羹nf Jahrzehnte eine rasanten Entwicklung erfahren. GPUs (auch als Parallelrechner bezeichnet) wurden zu Beginn ihrer Entwicklung als eine Entlastung der Central Processing Unit (CPU) bei der Berechnung von Grafiken konzipiert. Derartige Grafik-Berechnungen (Voxel-Berechnungen, Kalkulationen von dreidimensionalen Volumengrafiken, etc) bestehen heruntergebrochen aus simplen und schrittweise stattfindenden Verrechnungen von Gleitkommazahlen innerhalb einer Fixed-Funciton-Pipeline. Die zunehmenden Anforderungen von Spiele- und Rendering-Engines (Unity, Blender, Cinema4D, etc) sowie eine Erh繹hung der Aufl繹sung heutiger Ausgabeger瓣te erfordern GPU-Architekturen, welche in der Lage sind immer gr繹?ere Mengen an Daten unter kleinstm繹glicher Latenz zu verarbeiten. Der hohe Durchsatz einer GPU - gemessen in FLOPS (Floating Point Operations per Second) - geht auf die besondere Eigenschaft der GPU zur羹ck, Daten parallelisiert nach dem Single Instruction Multiple Thread (SIMT)-Prinzip verarbeiten zu k繹nnen. Anspruchsvolle Textur- und Voxel-Berechnungen werden - zun瓣chst vereinfacht betrachtet - als ein teilbares Gesamtproblem auf die vielen Rechenkerne der GPU aufgeteilt, als Bruchst羹cke berechnet und zuletzt wieder zu einem Ergebnis zusammengef羹gt. Nicht zuletzt hat diese Art der alternativen Prozessierung (im Vergleich zur Multiple Instruction Multiple Data (MIMD)-basierten Datenverarbeit

Einsatzgebiete und Grenzen des Cloud Computing in Unternehmen
Studienarbeit aus dem Jahr 2021 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,0, AKAD University, ehem. AKAD Fachhochschule Stuttgart, Sprache: Deutsch, Abstract: Das Ziel dieser Arbeit ist es, die Einsatzgebiete und die Grenzen des Cloud Computings aufzuzeigen. Dabei soll untersucht werden welche Cloud Service- und Liefermodelle es gibt und welche Vor- und Nachteile insbesondere letztere haben. In diesem Zusammenhang soll auch skizziert werden, wann es sich f羹r ein Unternehmen eher nicht empfiehlt Cloud Computing einzusetzen. Cloud Computing hat das Stadium eines Trends 羹berwunden. Die neue Art der Dienstleistungserbringung disruptierte den Markt. Anstatt "Cloud first" hei?t es heute unternehmens羹bergreifend "cloud only". Schritt f羹r Schritt ver瓣ndert das Cloud Computing die Welt und stellt bestehende IT-Infrastrukturen auf den Pr羹fstand. Unternehmen erkennen zunehmend die M繹glichkeiten Daten fernab eigener Datenbankkapazit瓣ten zu verarbeiten. Welche Risiken die Unternehmen dabei eingehen, und wo Grenzen des Cloud-Computings liegen, ist vielen oft nicht bewusst.
